Objective : The purpose of this study was to identify the relationships among cognitive function, activities of daily living (ADL), participation and quality of life in community-dwelling elderly. Methods : Cognitive function, ADL, participation and quality of life were assessed in the 144 elderly people residing in the community. We used MMSE-K for measuring cognitive function, K-ADL for ADL, K-ACS for participation, and GQOL for quality of life. Results : Cognitive function was significantly correlated with social activity of participation and quality of life (physical health, psychological health, social relations and economic level). ADL was significantly correlated with participation (instrumental ADL, leisure activity) and all sub-areas of quality of life. Social activity of participation were significantly correlated with all subarea of quality of life except physical health. Among the variables, the most relevant variable was leisure activity. Conclusion : It was related to quality of life in the order of participation, ADL, and cognitive function. Among the sub-areas of participation, leisure activity was the most correlated with quality of life. This study, thus, aimed to provide basic data for successful elderly life by examining the correlation between cognitive function, daily life activity, participation and quality of life in community-dwelling elderly.

The aim of this study was to investigate the relationship between compassion fatigue, compassion satisfaction, spirituality and quality of life in nursing students with clinical practice. Participants were 172 fourth-year nursing students who were recruited from 3 universities. Data were collected using self-reported questionnaires from November 7 to December 11 in 2020. The results show that burnout was negatively correlated with quality of life and compassion satisfaction was positively correlated with quality of life. In addition, spirituality was negatively correlated with burnout and was positively correlated with compassion satisfaction. In order to improve the quality of life of nursing students, it is necessary to develop and apply a spirituality promotion strategy that can control compassion fatigue and compassion satisfaction along with the enhancement of compassion competency in the undergraduate course

This research aims to investigate the structural relationship among service quality, service value, satisfaction, relation quality and re-use intention and to establish the conceptual framework for the relationship between customer and service supplier. This research employs LISREL 8.30 for an empirical approach. With consumers in beauty shops supplying intangible and autonomous-oriented services, it was found that (1) perceived service quality was positively related to service value, satisfaction, relation quality and re-use intention, (2) service value encouraged satisfaction and relation quality, (3) satisfaction and relation quality showed relationship with re-use intention while no relationship between service value and re-use intention was tested, (4) re-use intention presented relatively strong relationship with relation quality geared from interaction between customer and service supplier than with customer satisfaction. Some implications of these results are discussed. Among others, it is noted that the small and customized firms must put their attention on relationship marketing.

The objectives of this study were to survey the level of social capital owned by self-support program participants, and to analyze the direct and indirect effects of social capital on their quality of life. Particularly because an individual's life is highly likely to be influenced by multiple aspects including human relation, this study purposed to determine the mediating effect of job satisfaction in the relation between social capital and the quality of life. The survey used a structured questionnaire, and in the contents of the questionnaire, the quality of life was selected as a dependent variable, social capital as an independent variable, and the job satisfaction as a mediating variable affecting the relation between social capital and the quality of life. The results of this study were as follows. First, as to the relation between self-support program participants' social capital and the quality of life, the network level and the normative level hand an important effect on the quality of life. Second, as to the relation between self-support program participants' social capital and job satisfaction, social capital had a negative effect on job satisfaction. Third, in the relation between self-support program participants' social capital and their quality of life, the mediating effect of job satisfaction was positive and this supports the spillover model among hypotheses on the relation between job satisfaction and the quality of life.

The purpose of this study was to analyze the effect of the consumer-brand relationship Quality (CBRQ) on the brand loyalty in the fast food restaurant in Masan, Korea. The Questionnaires were distributed to 250 students in the K University located in Masan, who were sampled by convenience-sampling method. The surveys were performed from December 6 to 14, 2004. The 246 Questionnaires were responded, and 12 unusable Questionnaires were excluded, then 234 were used for the final analysis $(response rate:\;93.7\%)$. For the statistical analysis, SPSS (12.0) was used to conduct the descriptive analysis, factor analysis, reliability analysis, Pearson correlation and multiple regression analysis. The result of this study showed that 2 constructs (satisfaction and commitment) of consumer-brand relationship Quality have significant positive effects on the brand loyalty in the fast food restaurant. It meant that as consumer-brand relationship quality becomes stronger, the customer's brand loyalty becomes greater. The differences of customer loyalty between the high and low group of self-connective attachment, satisfaction, commitment, trust and intimacy were significant. So the brand loyalty of high group of customer-brand relationship quality was significantly higher than that of low group of customer-brand relationship quality. As a conclusion, the operator in the fast food restaurant should focus on the marketing strategy to strengthen the quality of consumer-brand relationship in order to increase the brand loyalty of customers.

Formal Concept Analysis (FCA) is a widely used methodology for data analysis, which extracts concepts and builds a concept hierarchy from given data. A concept consists of objects and attributes shared by those objects, and a concept hierarchy includes information on super-sub relations among the concepts. In this paper, we propose a method for extracting Implication and Association rules from a concept hierarchy given a query by a user. The method also describes a way for displaying the extracted rules. Based on this method, we implemented an automatic tool, QAG-Wizard. Because the QAG-Wizard not only elicits relation information for the given query, but also displays it in structured form intuitively, we expect that it can be used in the fields of data analysis, data mining and information retrieval for various purposes.

In this paper, we propose a new intelligent query processing system for relational database !systems. By analyzing previous research results related with fuzzy queries, a new intelligent query processing sysytem is developed and the role of each module including intelligent query processor is defined and :some algorithms for parser, query translation module, inference engine, semantic DB and result com-poser are suggested. By applying a typical example to the proposed intelligent query processing liysytem, reasonable results for the ambiguous query are drawn, and therefore it shows a promising model returning ordered result for both the ambiguous queries and general queries.
